【Abstract】 The dyeing and adsorption character of kapok fiber with direct dyes were discussed in the paper.The results showed that the dyeing process of kapok fiber with direct dyes Solophenyl Blue,Red 3BL and Black FR could be explained by pore diffusion model and it could be accelerated by salt.The adsorption isotherm of direct dyes Solophenyl Red 3BL on kapok fiber was similar to the type of Freundlich adsorption isotherm.更多还原
